Book Description
This book gathers original contributions from a selected group of distinguished researchers that are actively working in the theory and practical applications of solvent effects and chemical reactions. The importance of getting a good understanding of surrounding media effects on chemical reacting system is difficult to overestimate. Applications go from condensed phase chemistry, biochemical reactions in vitro to biological systems in vivo. Catalysis is a phenomenon produced by a particular system interacting with the reacting subsystem. The result may be an increment of the chemical rate or sometimes a decreased one. At the bottom, catalytic sources can be characterized as a special kind of surrounding medium effect. The materials involving in catalysis may range from inorganic components as in zeolites, homogenous components, enzymes, catalytic antibodies, and ceramic materials. . With the enormous progress achieved by computing technology, an increasing number of models and phenomenological approaches are being used to describe the effects of a given surrounding medium on the electronic properties of selected subsystem. A number of quantum chemical methods and programs, currently applied to calculate in vacuum systems, have been supplemented with a variety of model representations. With the increasing number of methodologies applied to this important field, it is becoming more and more difficult for non-specialist to cope with theoretical developments and extended applications. For this and other reasons, it is was deemed timely to produce a book where methodology and applications were analyzed and reviewed by leading experts in the field.

Book Description
In Solvent Effects in Chemistry: Advances in Applications and Research, a critical review of solvent influence on the performance of metal catalysts in the hydrogenation of carbonyl compounds, specifically unsaturated aldehydes, ketones and ketoesters, is provided.Additionally, the effects of solvent on the kinetics and mechanism of different reactions, stability, and sensitivity of the nanostructures are investigated.The uses of a large of variety of solvents varying from non-polar low basic solvents to polar strong basic solvents are discussed, showing that the properties of different solvents strongly influence the product composition of both studied reactions.The effects of solvent on the isomerization of monoterpenes epoxides as α- and β-pinene epoxide, limonene epoxide, verbenol epoxide, and nopol epoxide are explained from molecular and mechanistic points of view.The concluding study explores how heterolytic bond dissociation forms ionic species, while the corresponding homolytic bond dissociation results in the formation of neutral radical species.

Book Description
In the 1970s, Density Functional Theory (DFT) was borrowed from physics and adapted to chemistry by a handful of visionaries. Now chemical DFT is a diverse and rapidly growing field, its progress fueled by numerous developing practical descriptors that make DFT as useful as it is vast. With 34 chapters written by 65 eminent scientists from 13 diffe

Book Description
This book introduces the concepts, theory and experimental knowledge concerning solvent effects on the rate and equilibrium of chemical reactions of all kinds. It begins with basic thermodynamics and kinetics, building on this foundation to demonstrate how a more detailed understanding of these effects may be used to aid in determination of reaction mechanisms, and to aid in planning syntheses. Consideration is given to theoretical calculations (quantum chemistry, molecular dynamics, etc.), to statistical methods (chemometrics), and to modern day concerns such as "green" chemistry, where utilization and disposal of chemical waste or by-products in an environmentally safe way is as important as achieving the desired end products by all chemists nowadays. The treatment progresses from elementary to advanced material in straightforward fashion. The more advanced topics are not developed in an overly rigorous way so that upper-level undergraduates, graduates, and newcomers to the field can grasp the concepts easily.

Book Description
Biphasic Chemistry and The Solvent Case examines recent improvements in reaction conditions, in order to affirm the role of chemistry in the sustainable field. This book shows that those who work within the chemistry industry support limits for the use of toxic or flammable solvents, since it reduces the purifications to simple filtrations. Thanks to commercial scavengers, solid phase syntheses are now available to all. Fluorine biphasic catalysis enables extremely efficient catalyst recycling and has a high applicability potential at the industrial level. This book also reviews the many studies that have shown that water is a solvent of choice for most synthetic reactions. Particular traits can be obtained and the effects on thermodynamics make it possible to operate at lower temperatures, thereby achieving energy savings. Finally the great diversity of application of the reactions without solvents is illustrated.

Book Description
This 4th edition of Handbook of Solvents, Volume 1, contains the most recent findings and trends in solvent applications. It is a comprehensive survey of the science of solvents and their properties, covering all aspects of solvent behavior that are relevant to their use in chemical and related industries including agricultural and technical processes, inorganic synthesis and materials chemistry, and more. Divided into two volumes, this first volume covers high-level information on the physical chemical properties of the most relevant solvent systems. Each chapter is focused on a specific aspect of solvent properties that determine its selection, such as the effect on properties of solutes and solutions, properties of different groups of solvents, and the summary of their applications' effect on health and the environment (given in tabulated form). Also covered is swelling of solids in solvents, solvent diffusion and drying processes, nature of the interaction of solvent and solute in solutions, acid-base interactions, the effect of solvents on spectral and other electronic properties of solutions, the effect of solvents on the rheology of the solution, aggregation of solutes, permeability, molecular structure, crystallinity, configuration, conformation of dissolved high molecular weight compounds, and the effect of solvents on chemical reactions and reactivity of dissolved substances. With insight from specialists in a broad array of different areas and written with an interdisciplinary audience in mind, this thoroughly revised 4th edition provides readers with a complete overview of all the organic solvents available for industrial applications today. The book contains numerous references to key sources of more detailed information, and together with Handbook of Solvents Volume 2: Use, Health, and Environment; Databook of Green Solvents; and Databook of Solvents, represents the most comprehensive and up-to-date information ever published on solvents. - Provides key insights that will help engineers and scientists select the best solvent for the job - Includes practical information and ideas on how to improve existing processes involving solvents - Presents the latest advances in solvent technology and their applications
